Abstract (en)
[origin: WO0140318A2] Method for producing an hydrophobically associative polymer is provided which is characterized by forming a monomer solution comprising a surfactant, at least one hydrophobic ethylenically unsaturated monomer, at least one hydrophilic monomer selected from nonionic ethylenically monomers, cationic ethylenically unsaturated monomers, anionic ethylenically unsaturated monomers or mixtures thereof, and water; forming a salt solution comprising a multivalent salt and water; mixing the monomer solution and salt solution to form a mixed solution; and charging the mixed solution with an initiator, thereby polymerizing the monomers to form the hydrophobically associative polymer in a dispersion. Aqueous dispersion containing the hydrophobically associative polymer formed by the method. The aqueous dispersion containing the hydrophobically associative polymer may be used in a paint formulation, in a mobility control fluid useful in enhanced oil recovery, in a secondary or tertiary oil recovery system, in an enhanced oil recovery method, in a cementious composition, in an oil well drilling mud formulation, in a fracturing fluid formulation, in a wastewater treatment system, or in a dewatering sludge system.
